c | Problem: P share too large Solution: → Rotate KP against 0 (fine adjustment) ➝ Use DIL 14–16 to reduce the P gain according to the table | |
d | Problem: P share correct, control deviation too large Solution: ➝ Increase the I gain share → DIL 11 ON = I share = 0 DIL 12 ON = I share connected → Rotate KI against 13 | |
e | Problem: Time constant of the I share too low Solution: ➝ Rotate KI against 13 until control deviation and vibration are perfect → If KI = 13 is not sufficient, the P share must also be reduced | |
f | Problem: D share too low Solution: ➝ Rotate KD against 13 → D share > | |
